The research focus of this project will be on the testing of low acoustic loss material for the construction of a massive "Truncated Icosahedron Gravitational-wave Antenna" (TIGA). The most promising TIGA fabrication process identified so far is to explosively bond a number of aluminum plates to build up a large block of aluminum from which to machine the TIGA. U.S. Industry has the capability to produce such material. The main emphasis of the research will be to test the acoustic loss of samples at cryogenic temperatures and attempt to find a fabrication process and post-fabrication processing that will allow the intrinsic low acoustic loss of aluminum to be retained in samples prepared by this technique. This characterization of this new material will be an important input for the planning of the next generation of acoustic gravitational-wave receivers throughout the world.

本项目的研究重点是测试用于建造大型“截角二十面体引力波天线”（TIGA）的低声损材料。 到目前为止，最有前途的TIGA制造工艺是将许多铝板爆炸性地结合起来，形成一大块铝，然后用它来加工TIGA。 美国工业有能力生产这种材料。 该研究的主要重点将是测试样品在低温下的声学损失，并试图找到一种制造工艺和制造后处理，使铝的固有低声学损失保留在通过这种技术制备的样品中。 这种新材料的特性将成为世界各地规划下一代声学引力波接收器的重要投入。
